When I buy a domain I usually try to get as many of the .ext as possible - I recently had an issue with a Chinese company saying they had copyright on one of my domain names. I was able to prove that I had registered my domains with that name long before they even existed. There is quite a trade in domain names and with so many of them taken now people are paying a lot to get the ones they want. Not sure if the new exts will help or not.
